I did a caapi leave soak in IPA, the tek said 2 weeks at least but the longer the better. So I took 10 gram of caapi leave and Crushed them in a jar, added IPA and left them in a dark drawer and shaked it ones a day for 2 months. The IPA had a dark green color on the end.

Is the green color normal?

I read the solution gets dark but never read it was green so just check-in?

As you can see in the picture the changa is almost ready. But would love a green light for liftoff

Green is a very normal colour to see after soaking leaves in IPA. The chlorophyll extracts very nicely that way.

The harmala alkaloids are not very soluble in IPA. You might want to try soaking the leaf matter in another portion of alcohol, although 10 grams of leaves in 'a jar' of alcohol might, depending on the size of the jar, suffice.
